To be fair to all of the fearful people bailing on stocks and driving down the price, the market has admittedly seemed a little overzealous recently, and the huge new deficits that republicans created with their tax bill are going to come home to roost eventually, and interest rates are still too low to let the fed effectively manage the next recession. There are real risks in the market.
OTOH, corporate profits are at record highs. Employment is up, production is up, and Trump hasn't poked North Korea with threats of nuclear annihilation in almost a month now. I think the US economy is fine, and stocks are due for a little correction. A 10% drop would probably be a good thing, right about now.
